Q. In an active water drive during a certain period, the rate of production and reservoir pressure remain constant. The water influx into the reservoir from the aquifer is 6000 bbl/day. The surface oil and water production rates are 3000 STB/day and 1500 STB/day, respectively. The current production gas to oil ratio is 825 SCF/STB, and the formation volume factors at the current pressure for oil, water and gas are 1.375 bbl/STB, 1.04 bbl/STB and 0.007 bbl/STB, respectively. The solution gas to oil ratio at the current pressure is____SCF/STB (round off to 1 decimal place).
Ans: 739-815
